EDEN PRAIRIE, Minn. --Scott Crichton's decision to declare for the NFL Draft was more difficult than usual.

Crichton, 22, left after his junior season at Oregon State to financially support his family, which he'll be able to do after the Minnesota Vikings selected him 72nd overall on Friday night.

"Told my Dad to retire," Crichton said via conference call. "I don't know about my Mom. She doesn't want to stay around the house. She might go back to one job, we'll see. We haven't got that far yet."

Crichton briefly explained the emotions of his father, who lost a leg to diabetes and works at a warehouse, while his mother works as a nurse at a retirement home.

Crichton (6'3", 265lbs) is one of the record 98 underclassmen who declared for the draft. He totaled 22.5 sacks, 10 forced fumbles and nine pass deflections in three seasons.

Registered a 4.84 in the 40-yard dash; 31.5-inch vertical jump and put up 24 reps on the 225lb bench at February's NFL Scouting Combine.

He had private workouts with the New England Patriots, Atlanta Falcons and Carolina Panthers as teams looked at him as an outside linebacker in a 3-4 fit. However, Crichton falls to the Vikings in Zimmer's 4-3 scheme as another edge rusher after the team took linebacker Anthony Barr with the ninth overall pick on Thursday.

Oregon State also plays a 4-3 scheme, one which Crichton played in as linebacker for a game during his freshman season.
